what are the roles & resonsibilities of dba in dataware housing

what database activities normal DBA should monitor
and control on dataware housing? is it(dataware housing) needs any extra database knowledge?

Well, for a start he would take care that every table has its primary key constraint set. So that he would be certain that no two rows with the same primary key would be inserted into the table.

Now in the last sentence above replace ROW with THREAD, PRIMARY KEY with SUBJECT and TABLE with DBA.SUPPORT.COM FORUM and you'll know what I mean....

Hm, I see you've got the point and deleted the other thread.

For all others: disregard my previous post, now it doesn't make sence any more.....

I deleted it so your post is still valid :D
